Definitions
- the method has the process steps: a) providing a pourable carrier material, in particular a granulate, b) arranging the carrier material between two belt-like conveyors, c) shaping the carrier material under the action of temperature to form a web-shaped carrier, d) compressing the carrier, e ) Treating the carrier under the action of pressure using a two-belt press, the carrier being cooled in or in front of the two-belt press, f) optionally further cooling of the carrier, g) optionally applying a decorative background to at least a partial area of the carrier; h) applying a decoration that simulates a decorative template on at least a partial area of the carrier, i) applying a protective layer to at least a partial area of the decor, j) optionally structuring the protective layer to insert pores and / or the edge area of the carrier to form connecting elements, and k) optionally treating the carrier for electrostatic discharge before one of the aforementioned process steps.
- the method described above enables an improved production of a wall or floor panel.
- high-quality panels with improved decorative properties can be obtained within very short process times.
- the panels have particularly even support surfaces on which high-quality decorations can be applied particularly efficiently.
- decorations applied according to the invention exhibit particularly high-quality optical properties due to the particularly smooth and fault-free surface of the carrier material.
- the procedure specified above also enables a high throughput at high web speeds and reduces the proportion of non-compliant panels.
- Examples of such modeled natural materials or decorative templates are types of wood such as maple, oak, birch, cherry, ash, walnut, chestnut, wenge or exotic woods such as panga-panga, mahogany, bamboo and bubinga.
- natural materials such as stones or ceramics can be modeled.
- the diameter of the main rollers and the downstream rollers is selected so that the contact surfaces between the carrier and the rollers are largely the same on both sides of the carrier.
- a decoration which simulates a decoration template is applied to at least a partial area of the carrier.
- the decor can, for example, by a so-called Direct print can be applied.
- Direct printing is understood to mean the application of a decoration directly to the carrier of a panel or to a non-printed fiber material layer or a decorative substrate applied to the carrier.
- Different printing techniques such as flexographic printing, offset printing or screen printing can be used.
- inkjet or laser printing processes for example, can be used as digital printing techniques.
- the decoration can be applied identically to the template after passing through the roller arrangement.
- the three-dimensional decor data can be provided by three-dimensional scanning of the decor template by means of electromagnetic radiation, for example by a three-dimensional scanner (3D scanner).
- a plurality of decorative layers with at least partially different surface application can be applied successively on the basis of three-dimensional decorative data provided.
- decorative templates such as wood-based materials, for example, often have a variation in the color impression not only along their width or length but also along their depth.
- this one Color impression or color gradient can be reproduced particularly true to detail in this embodiment in particular, which also makes the overall impression of the panel appear even more identical.
- the color or ink used is radiation-curable, particularly rapid solidification can be achieved, whereby the majority of layers can be applied quickly to one another, which can also make the overall process realizable in a shorter time and thus particularly cost-effective.
- a corresponding negative image of the decorative template is also applied.
- the use of digital data can be used to reverse the color impression, for example of a grain, so that a negative is created with regard to the color or, in particular, lighter and darker areas.
- the applied structure so that a negative can also be realized with regard to the structural design. Effects of this kind can also be integrated into a manufacturing process on the basis of digital three-dimensional data without problems and without lead time or modifications.
- a protective layer is applied to at least a partial area of the decoration.
- Such a layer to protect the applied decoration can in particular be applied as a wear or cover layer above the decorative layer in a subsequent process step, which in particular protects the decorative layer from wear and tear or damage from dirt, the influence of moisture or mechanical effects such as abrasion.
- the wear and / or cover layer is placed on the printed carrier as a pre-produced overlay layer, for example based on melamine, and is connected to it by the action of pressure and / or heat.
- a radiation-curable composition such as, for example, a radiation-curable lacquer, such as an acrylic lacquer, is also applied to form the wear and / or top layer.
- a transparent wear layer made of thermoplastic polymers can also be used, which is laminated onto the decorative layer as a film web. It may be necessary to use an adhesion promoter / primer for adequate adhesion, which is crosslinked with the decorative layer by radiation curing from above (“adhesive varnish”) or thermally sealed (“hotmelt”).
- a thermoplastic wear layer offers further advantages for the recycling process of the overall structure. A surface structuring can be introduced very easily via heated, structured metal sheets using a press or structured rollers using a calender (this also synchronized with the decor).
- the carrier plate provided with a decoration can then be divided into individual panels by suitable mechanical processes. This can be done, for example, by cutting the extruded strand at regular intervals or at regular times. This process step can preferably be used to produce cut panels of the same length.
- ethylenically unsaturated structural units are acryloyl and methacryloyl groups such as acrylamido and methacrylamido and in particular acryloxy and methacryloxy.
- Radiation-curable in the context of the invention means that the primer composition can be at least partially polymerized induced by electromagnetic radiation of a suitable wavelength, such as, for example, UV or electron radiation.
- the primer can preferably be applied by means of rubber rollers, a casting machine or by spraying onto the carrier plate running through the roller arrangement. It is also possible that the primer is applied after the roller arrangement but before the decoration is applied.
- the primer is preferably used in an amount between> 1 g / m 2 and ⁇ 100 g / m 2 , preferably between> 10 g / m 2 and ⁇ 50 g / m 2 , in particular between> 20 g / m 2 and ⁇ 40 g / m 2 applied.
- a preferred embodiment for the device can comprise a temperature-controllable screw extruder and a slot die with variable profile.
- the device can have rollers that can be temperature controlled and, in particular, be cooled.
- the individual rolls can be moved relative to one another in their positions in the production process and consequently the dimensions of the roll gaps formed between the rolls can also be changed.
- at least one larger pair of main rollers and several, preferably at least 3, more preferably 4, furthermore preferably 5 further, smaller calibration rollers can be used for shaping and calibrating the carrier.
- the rollers can each be equipped with adjustable temperatures.
- the solid material is formed to at least 50% by weight, in particular at least 80% by weight, in particular at least 95% by weight, based on the solid material, from a solid composition consisting of at least one first Layered silicate powder and a second layered silicate powder.
- Talc in particular, has the advantage that it enables the carrier to be produced in a particularly gentle manner, since it can be embedded in the matrix material without any problems and thus does not exert any abrasive effect on the press units used.
- a panel can be provided which has a flexural modulus of> 3000 MPa to ⁇ 4000 MPa, preferably from> 3400 MPa to ⁇ 3600 MPa. It can also be achieved that panels produced with the carrier material have an advantageous flexural strength.
